HAT-BODY-ROUNDING MACl-HNE.

QPECIFICATION forming part of Letters Patent No. 298,795, dated May 20,1884-. Application filed September 29, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, ALFRED 'l. STURDE- VANT, a citizen of the UnitedStates, residing at Oroton Falls, in the county of VVestchester andState of New York, have invented certain new and useful Improvements inHat Body- Rounding Machines; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to certain novel and usefulimprovements in machinesfor rounding hat-bodies, and has for its object to provide such amachine which shall effect a uniform shear out, while at the same timeit may be so adapted that hat-bodies of various sizes may beaccommodated, or the out may be made to any desired depth; and withthese ends in view my invention consists in the details of constructionand combination of elements hereinafter fully and in detail explained,and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertainsmay understand more fully its construction and operation, I will proceedto describe the same, referring by letters to the accompanying drawings,forming part of this specification, in which Figure 1 is a plan View ofmy improvement, illustrating more particularly the platform upon whichthe hat-body is clamped; Fig. 2, a View showing the platform andmechanism for adjusting the same in section and the cut ting-disks andmeans for operating the same in side elevation; Fig. 3, a detail view ofthe cutting-disks in operative position; and Fig. 4,a detail view of thetraveling block,showing the graduated scale.

Similar letters of reference denotelike parts in the several figures ofthe drawings.

A is the bed-plate of the machine, having projecting therefrom standardsB, within which are journaled the shafts O D in any ordin ary way.

E is a driving-pulley mounted, preferably, on the upper shaft.

F are cog-wheels mounted on said shafts so as to mesh, the object ofthis construction being to communicate motion from the upper shaft tothe lower.

G are cutting-disks secured on the inner extremities of the said shaftsin such manner as to make a shear cut.

H is an elongated slot within the bed-plate, and within this slot is atraveling block, I, to the bottom of which is secured or cast integraltherewith a nut, J, for the purpose presently explained.

K isaplatform or table, of any suitable shape or contour, and swivellyconnected atits rear portion to the top of the traveling block I.

L is a threaded rod journaled within bearings M and operating within thenut J. This rod is confined as against longitudinal movement by means ofcollars N The threads in the nut and on the rod are in the samedirection, but of the opposite nature, so that it will be readilyunderstood that the action of the rod within the nut will slide theblock back and forth, as the case may be. For convenience inmanipulation I secure a wheel, 0*, 011 the rod, as shown.

P Q are gages, by means of which hat-bodies of different sizes may beaccommodated. These gages consist of plates of metal or other suitablematerial slotted longitudinally and arranged to slide on the surface ofthe platform or upon proper bearings, as may be desired, and clamped inany required position by means of set-screws R, passing through saidslots or otherwise arranged so as to bear directly upon the said plates.Along the line of movement of these gages Ipreferably make a graduatedscale, by means of which the ad justments for hat-bodies of differentsizes may be determined.

Sis a spring-clamp, underneath which is placed the hat, as shown at Fig.1, and by means of which the hat-body is firmly held during theoperation of cutting.

The operation of my improvement is as follows: I raise the said clampand insert the hat so that the peaked or tip part shall abut against thegage P, and the sides be confined by the gages Q, as clearly shown atFig. 1. If a large hat-body is to be operated upon,I run the gage Pbackward to accommodate the depth of the hat-body and likewise adjustthe gages Q to allow for the width. The traveling block is then adjustedby means of the rod L, as hereinbefore set forth, in order to bringtheplatform in its revolution nearer to or farther away from thecutting-disks for the pur poses of taking a greater or less cut, as maybe desired. The platform is then swung toward 5 the revolvingcutting-di'sks,and the lower portion of thehat-body which protrudesisfed between said disks and cut on a perfect are. No feeding of thehat-body by hand between the cutters is necessary after the latter haveonce 1 0 come in contact with the hat-body, because they will continueto draw the hat-body toward them until it has been entirely out around.

Prior to my invention hat-bodies have been rounded by cutting off byhand with knives; but this is not only tedious and expensive, but thecut so formed is not regular or the same 'in all cases, and additionaltrimming is generally required.

By the use of my improvement the manu- 20 better class of workisproduced. cutters becomev dull, they may be readily removed andsharpened or new ones substituted therefor.

Havingthus described my invention, what I claim as new, and desire tosecure by Letters Patent, is. j

1. In a device for. rounding hat-bodies, the combination of means forholding the hat-body o mechanism, substantially as set forth.

2. In adevice for rounding hat-bodies,meansv for holding the hat fiat inits cone shape upon hat flat in its cone shape against said platfactureof hats is notonly cheapened, but a Should the fiat upon a revolvingplatform and the cutting the platform, and adjustable gagesfor confiningthe hat as against horizontal displacement, substantially as set forth.

3. In a device for rounding hat-bodies, the swiveled platform adapted tosupport the hat, in combination with means for clamping the 0 form,adjustable gages to prevent horizontal displacement of the hat, andmechanism for cutting the hat-body, substantially as and for the purposeset forth.

4. The table K, swivelly attached to the ad- 5 justable block I, andhaving secured thereto the clamp S and gages P Q, in combination withthe cutters G, substantially as shown and described.

5. The clampS- and gages Q, attached to the platform, asshown, wherebythe-hat-bod-y may be held and different sizes-accommodated, incombination with means for adjusting said platform and mechanism forcutting the hatbod-y, substantially as described.

6. The clam-p Sand gages Q, attached tothe platform, as-shown, wherebythehat-body may be held and different sizes accommodated, substantiallyas set forth.

In testimony whereof I affix my signaturein 6o presence of twowitnesses.
